ROLLER CONVEYER.

` To all 'whom t may concern."

Be it known that I, GEORGE W. CURTIS, la citizen of the United States,and a resident ofthecity of Canton, in the county of Stark and State'ofOhio,have invented a new and useful Improvement in Roller Conveyers, of

be easily adjusted. Further objects of .the

mvention are to devise means rvfor lubricating the bearings and meansfor permltting easy removal and replacement of any worn parts.

The invention vconsists principally inf 'mounting the bearings of eachset of conveyer rollers so that the adjustment ofall .of the bearingsmay be'made from the endmost bearing. The invention further consists inthe parts and combinations of parts hereinafter described and claimed.

In thev accompanying drawing,

Fig. 1` is a sectional View of a setfof conveyer rollers embodying myinvention, the supports therefor being shown in elevation;

, Fig. 2 is, a sectional View on the line 2 2 of Fig. 1; and f Fig. 3 is.a sectional view Yon the line 3-3 of Fig. 1.

Mounted on a suitable base 1 are brackets 2 that support avsetofvconveyer rollers 3.

In the drawing a set of five conveyer rollers 3 is shown. The brackets 2have recesses 4' in--which are disposedv the ends of. tubes 5 on whichthe vconveyer rollers are mounted.

.The end vrollers are supported at one end only, the outer ends beingfree.

The conveyer rollers 3 are shown as hollow webbed members with4 a.central hub 6. The hub' member 6 has enlargedopenings .7 at the endsadapted to receive the cup 8 of a conical roller bearing, said cups'abutting against shoulders 9l at the inner end' of the openings inwhich they rest. Mounted on the tubes 5 are roller bearing-cones 10, anda set of con-ical anti-friction rollers 11' is interposedjbetween each.pair .of oups and cones.

'Mounted on the ends of the tubes 5 that extend into the brackets arethimbles 12 or spacing memberseach of which has a flanged' vend 12a thatabutsv against the end of a roller bearing cone 10. The ends of adjacentthmbles 12 abut against each other in the bracket recesses,.and thusserve to` locate kthe rollers properly and hold them in positionendwise. The thimbles 12 and ends 0f the tubes 5 have holes therethroughinto which extend the ends of screws 14 that are mounted in thebracketsj2. The holes in v.

-the tubes are of the exact size required to it the-screws 14, so thatsaid tubes are held againstmovement in every direction. The holes in thethimbles 12 are considerably larger than the screws 14, so that movementof the thimbles is permitted.

Mounted on-the outer end of each of the,

outermost bearings is an adjusting nut- 15 that is provided with alscrew 16 for holding it inl position. '.lu'rning said adjusting nutmoves the endmost cone on its tube 5 and thus adjusts the bearing. Whenthe outer most bearing is adjusted, continued turning of the yadjustingnut moves the entire outermostv bearing along the tube carrying the end'conveyer roller with it, and thus the. i

force is 'transmitted tothe cup of the second bearing and said secondbearing is adjusted. By means of the contacting thimbles, furtherturning of the adjusting nut adjusts the first bearing of the adjacentvconveyer roller, and further turning carries the adjustment to the 'nextbearing. In this way all of' the bearings may beadjusted by turning theadjusting nut at either -end of the set.

of the' set toward the middle, instead of makingthewhole adjustment fromone end. l The end of each outer tube 5 isy closed by a grease-retainingscrew 17 of the ordinary type used in pressure lubrication. v The :tubesare perforated at about their middles to permitlubricant toescapetherefrom on tothe roller bearings. The thimbles are perforated ltopermit lubricant to pass from one .tube to the next tube; so that all ofthe roller bearings may be lubricated byv means In. practice, adjustmentis made from each end cant. A washer 19 is preferably interposed betweeneach adjusting nut' 15 and the adjacent bearing cone. v The conveyer isassembled as follows;

l One of the innersupporting brackets 2 is `olaced in position, andthevend of the tube 5 that supports the middle conveyer roller 3 withthe bearing members 8, 10, 1l, roll 3, thimbles 12, and grease retainers18 correctly assembled thereon is placed in position. The other innersupporting bracket 2' is then placed in position; and then the nextassembled conveyer rollers 3 are inserted in place. The outer bracketsare then put in position and the endmost conveyer rollers placedtherein. The screws 14 are lthen turned so that all of the tubes areproperly secured in position; and then the supporting brackets areiirmly secured to the base. Adjustments of the bearings and lubricationthereof are accomplished as hereinbefore described. Y j

'llhe roller conveyer liereibefore described lias numerous advantagr s.rllie conveyer rollers are properly spaced and located by means of thethimbles. The roller bearings are easily adjusted; so that looseness of'the parts may be prevented. ln case of damage to any part, it may easilybe removed and another part inserted in its place. Obviously numerouschanges may be made without departing from the invention and l do notWish to be limited to the precise construction shown.
